The BA and BF XR6 Turbo has tremendous potential, which can quickly be unleashed with the fitment of the Manta Performance Exhaust System. The full turbo back system replaces the entire standard exhaust system, freeing up the turbo and reducing lag, whilst improving top-end performance and reducing fuel consumption due to its higher flowing design that allows the engine to operate more efficiently. The exhaust note is much improved, allowing the whistle of the turbo to be heard. The two high-flow mufflers used ensure minimal in-cab drone, yet still maintain maximum flow and performance. The dump pipe-back system suits more moderate applications, replacing the restrictive catalytic converter with a high flow version, whilst keeping the factory dump pipe. The cat-back system is also available, which bolts on behind the standard dump pipe and catalytic converter. The cat-back still gives a moderate increase in performance, while improving the sound of the vehicle, allowing that 6-turbo exhaust note to really be heard. For extreme applications, the dual 3? system offers the highest flow possible, and is the only true dual 3? exhaust system on the market for the XR6 turbo. All 2.5? systems are available in either stainless steel and aluminised steel, with the stainless exhaust systems carrying a 10 year warranty against manufacturing defects. In reality, a stainless system should last the life of the vehicle.
